Monopsony and the wage effects of migration

In a generalization of the well-known “immigration surplus” result, we show immigration must always increase the average native worker’s marginal product, in any long-run constant returns economy. But in a monopsonistic ...Read more...

The contribution of immigration to local labor market adjustment

The US suffers from persistent local disparities in employment rates, which should in principle be eliminated by population mobility. Can immigration accelerate this process? Remarkably, on average since 1960, new immigr...Read more...

Immigration, local crowd-out and undercoverage bias

Using decadal census data since 1960, I cannot reject the hypothesis that new immigrants crowd out existing residents from US commuting zones and states one-for-one. My estimate accounts explicitly for dynamic local adju...Read more...

Commuting, migration and local joblessness

Britain suffers from persistent spatial disparities in employment rates. This paper develops an integrated framework for analyzing two forces expected to equalize economic opportunity across areas: commuting and migratio...Read more...

The contribution of foreign migration to local labor market adjustment

The US suffers from large regional disparities in employment rates which have persisted for many decades. It has been argued that foreign migration offers a remedy: it “greases the wheels” of the labor market by accelera...Read more...

American Economic Review:

The persistence of local joblessness

Differences in employment-population ratios across US commuting zones have persisted for many decades. We claim these disparities represent real gaps in economic opportunity for individuals of fixed characteristics. Thes...Read more...

The persistence of local joblessness

Local differences in US employment-population ratios and unemployment rates have persisted over many decades. Using decennial census data from 1950-2010, we investigate the reasons for this. The persistence cannot be exp...Read more...

Why are higher skilled workers more mobile geographically? The role of the job surplus

The skill gap in geographical mobility is entirely driven by workers who report moving for a new job. A natural explanation lies in the large expected surplus accruing to skilled job matches. Just as large surpluses ease...Read more...
